We had heard good things about Costeaux and were excited to try breakfast in Healdsburg on our way to Russian River Valley wineries. After a 10 minute wait for acknowledgement, our server condescended to bring menus without bothering to speak to us. We ordered a mocha and a coffee and told him we wished to order a pastry, at which point he turned away without speaking and threw our menus on the stand beside the cash register. We didn't know if he was going to bring us our drinks or not, so we went inside to order our pastries, since no offer was made to tell us what was available. Miraculously, our drinks did appear at our table while we were inside, but our server continued to sulk and pout. I wanted to ask him if he needed a "time out." Better pastries and more courteous service was available at Whole Foods in Sonoma.
